Hi Mario
Well in principle it should work!!
I have made the Lime Mini work very well on ordinary simplex and had several QSOs on 2m.? I can send you a bit of code that implements this in the hardware file for Quisk if that might be helpful.? Quisk also has a feature to work with repeaters, thus using different frequencies for tx and rx which is what you must need for your application.? I have tried to use this but have never quite been successful.? The reason, I am almost certain, is that my understanding of Python/Quisk is not good enough.? Not too sure about the frequency stability for ssb and narrower modes but Lime can be phase-locked to a better standard.? The project here is to lock it to an old Rb standard.
Several UK stations use Pluto in set-ups for the Q0-100 satellite, with success.? There is also a question of stability and most replace the 40MHz source with better tcxo, which is not too difficult.? For alternative software see by Colin g4eml.? This employs a RaspberryPi and the software is very user-friendly.? I am almost certain that the newest version will work with Lime.? A downside is that the frequency display on-screen is restricted to ~ 200kHz.? It will implement rx/tx frequency shifts abut I do not know over what range.? The kit will run approx. 50MHz -- 5GHz.
Please let me know how you get on,
